Gram-negative folliculitis is an acneiform eruption.[1]

It occurs in people who have had moderately inflammatory acne for long periods and have been treated with long-term antibiotics, mainly tetracyclines. Cultures of lesions typically reveal a species of Klebsiella, Escherichia coli, Enterobacter, or, from the deep cystic lesions, Proteus.[2]: 242, 273
